AWSEC2LaunchTemplateInstanceMetadataOptions

@interface AWSEC2LaunchTemplateInstanceMetadataOptions

The metadata options for the instance. For more information, see Instance Metadata and User Data in the Amazon Elastic Compute Cloud User Guide.

  • This parameter enables or disables the HTTP metadata endpoint on your instances. If the parameter is not specified, the default state is enabled.

    If you specify a value of disabled, you will not be able to access your instance metadata.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
        AWSEC2LaunchTemplateInstanceMetadataEndpointState httpEndpoint;

    Swift

    var httpEndpoint: AWSEC2LaunchTemplateInstanceMetadataEndpointState { get set }
  • The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.

    Default: 1

    Possible values: Integers from 1 to 64

    Declaration

    Objective-C

    @property (readwrite, strong, nonatomic)
        NSNumber *_Nullable httpPutResponseHopLimit;

    Swift

    var httpPutResponseHopLimit: NSNumber? { get set }
  • The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional.

    If the state is optional, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

    If the state is required, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
        AWSEC2LaunchTemplateHttpTokensState httpTokens;

    Swift

    var httpTokens: AWSEC2LaunchTemplateHttpTokensState { get set }
  • The state of the metadata option changes.

    pending - The metadata options are being updated and the instance is not ready to process metadata traffic with the new selection.

    applied - The metadata options have been successfully applied on the instance.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
        AWSEC2LaunchTemplateInstanceMetadataOptionsState state;
